Title: Eiji Hosaka: Innovator in Motion Guide Technology
Introduction
Eiji Hosaka is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of motion guide technology, holding a total of 9 patents. His innovative designs have enhanced the functionality and efficiency of various mechanical systems.
Latest Patents
One of Hosaka's latest inventions is a linear movement guide device. This device features a track rail and a slider block that can move relative to the rail through multiple rolling bodies. It includes a position-determining pin that restricts the relative movement between the slider block and the track rail. The track rail is designed with a securing hole for attachment to a base member and a position-determining hole for the pin. The slider block also incorporates a rocker bearing part and a connecting hole for the position-determining pin, strategically positioned to avoid the center of the slider block in its lengthwise direction.
Another notable invention is a motion guide device that includes a track member with a recess or protrusion formed longitudinally. The moving member has a corresponding holding protrusion or recess. When force is applied that would separate the two members, the holding feature ensures they remain connected, resulting in a compact motion guide device capable of withstanding strong external loads.
